SUCTION-CLEANER.

Specification of Letters Patent.

Application filed October 25, 1910.

Patented Nov. 14, 1911. Serial No. 588,975.

To all whom it may concern:

Be it known that 1, JOHN B. POWELL, a citizen of the United States, residing at Philadelphia, county of Philadelphia, and State of Pennsylvania, haveinvented certain new and useful Improvements in Suction-Cleaners, of which the following is a specification.

My invention relates to improvements in suction'cleaners, the object of the invention being to provide improved suction or partial vacuum creating means which will insure a continuous suction through the dust collector and which can be easily operated.

A further object is to provide an improved diaphragm pump suction chamber having diaphragm pumps at opposite sides of an intermediate chamber, and provide improved means for operating the pumps in opposite directions whereby a continuous suction is had.

A further object is to provide an improved arrangement of levers, and link, and improved mechanism for imparting a reciprocating motion to the link, and simul-' taneously operate the pumps in opposite directions by means of the said levers, which are connected to the bellows.

With these and other objects in view, the invention consists in certain novel features of construction and combinations and arrangements of parts, as will be more fully hereinafter described and pointed out in the claim.

In the accompanying drawings: Figure 1, is a view in longitudinal section illustrating my improvements. Fig. 2, is a view in section on the line 22 of Fig. 1, and Fig. 3, is a view in section on the line 33 of Fig. 2.

1, represents a tank mounted on suitable supports 2 and provided with an internal annular ring 3. In the upper end of tank 1, "a dust collecting bag 4 is secured by the ordinary cover 5, and the dust laden air is sucked through the inlet 6, and through the bag by means of my improved mechanism which will now be described.

A plate or disk 7 is secured by screws 8 to the ring 3, and a gasket 9 is interposed between said plate and ring to make the joint tight. This plate or disk 7 is provided with a central rectangular opening 10 which registers with a U-shaped suction chamber 11 secured to the plate by means of screws 12 and clamping an interposed gasket 13 to render the juncture air tight.

\Vhile I refer to the chamber 11 as being of U-shape, it is as a matter of fact rectangular with its open end communicating with the opening 10. The opposite side walls of this chamber 11 are provided with a plurality of openings 14, and rubber sheets 15 are held against the outer face of said walls by means of angular frames 16 secured against the outer face of the chamber 11 and clamping the rubber sheets 15 in place, These rubber sheets 15 are provided with openings 17 which are out of alinement with the openings 14, so that the rubber sheets operate as valves to control the passage of air through openings 14 and 17 as will hereinafter appear.

The rectangular frames 16 are secured to the chamber 14 by means of rods 18 which are threaded at their inner ends and screwed into threaded sockets in the casing 11, said rods projecting through openings in the frames 16, and also through openings in the angular frames 19, and secured by means of nuts '20. Between these angular frames 19 and the frames 16, leather sheets 21 are securely clamped, and these leather sheets are provided with openings which register with openings in rubber sheets 22, the latter being clamped between the leather 21 and metal plates 23 by means of angular frames 24 and clamping screws 25, so that the frames 24, leather sheets 21, rubber sheets 22, and plates 23 are compelled to move together.

The plates 23 are provided with a plurality of openings out of register with the openings in the leather sheets 21 and rubber sheets 22, said rubber sheets acting as valves for said openings and the leather sheets with the parts carried thereby, constituting diaphragm pumps.

Each frame 24 is provided with an outwardly projecting yoke frame 25 having a lug 26 thereon. Each lug is pivotally connected to a lever 27 between the ends of the latter. Levers 27 are pivotally connected to brackets 28 depending from plate 7, and the lower ends of these levers 27 are connected by a link 29. On this link 29 a vertical guide 30 is fixed, and in which a block 31 is mounted to reciprocate.

The block 31 is connected by a crank pin 32 on a disk 33 secured to a shaft 34. The

shaft 34 is mounted in a bracket 35 secured to casing 11, and is provided at one end with a pinion 36, and back of said pinion a balance wheel 37 is secured on said shaft 34.

A large driving gear 38 is mounted to turn on a ournal bolt 39 secured in abracket 40 on casing 11. This gear 38 meshes with the pinion 36. lVhen the gear is turned, motion is transmitted to shaft 34, as will be hereinafter explained.

The hub 41 of the gear 38 is provided with screw-threaded sockets to receive screws 44 securing a cap 42, which incloses a nut 43 on one end of the journal bolt 39. This cap 42 is provided with an angular stub 45, on which a crank arm 46 is secured by means of a nut 47. It is to be understood, of course, that the cap 42 projects through an opening 48 in casing 1, and that the crank arm 46 is outside of the casing.

In operation, as the crank arm 46 is turned, gear 38 will be turned to transmit a rotary motion to pinion 36 and shaft 34. The disk 33 011 shaft 34 moves the crank pin 33 in the arc of a circle causing block 31 to reciprocate in bearing 30, and reciprocate the link 29 causing the levers 27 to oscillate and move the pumps in and out to create a suction through chamber 11 sucking the dust laden air through bag 4, and 1loeaving the dust and foreign matter in the It will be noted that by reason of the particular arrangement of parts, that one pump is always sucking the air regardless of the direction of movement so that a continuous suction is had to draw the dust laden air through the bag.

Various slight changes might be made in the general form and arrangement of parts described without departing from my invention, and hence I do not limit myself to the precise details set forth, but consider myself at liberty to make such changes and alterations as fairly fall within the spirit and scope of the appended claim.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent is:

A pump for suction cleaners, comprising a suction chamber, having openings in its opposite walls, frames secured to the outer faces of said suction chamber, sheets offlexible material clamped between said frames and the suction chamber, and having a plurality of openings out of register with the openings in said chamber, angular frames on the outer ends of said first-mentioned frames, sheets of flexible material secured between the first said frames and said angular frames, other angular frames of smaller dimensions arranged against the outer faces of said last-mentioned flexible sheets, rubber sheets against the inner faces of said last-mentioned sheets, said flexible sheets and said rubber sheets having registering openings, metal plates located against the inner faces of said rubber sheets and fixed to the last said angular frames, said plates having openings out of register with the openings in said sheets, and means for operating said plates and connected frames, substantially as described.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
